Government will kick-start a number of new infrastructure projects including 8 new airports and two new sea-ports in the coming months to boost sluggish economic growth, Prime Minister Manmohan Singh said on Thursday.

With economic growth slowing to a decade low of 5 per cent, the Congress-led UPA government has further opened the economy to foreign direct investment and now wants to use investments for returning to high growth trajectory.

"We will start work on a number of new infrastructure projects in the coming months. This includes 2 new ports, 8 new airports, new industrial corridors and rail projects," Singh said in his address to the Nation from the ramparts of Red Fort on the occasion of 67th Independence Day.

In several sectors such as oil refining, commodity exchanges and single-brand retailing, FDI has been allowed under automatic route rather than requiring official approval.

"In the coming months, we will see visible results of these efforts to increase investment. Our growth will accelerate, new employment opportunities will be generated and there will be improvements in the infrastructure growth," he said.

The Prime Minister said that government has recently taken several steps to speed up the process of government clearances for industry, build an environment more conducive to trade and industry and increase investment in the economy.

"A special cell has been set up to help big projects with clearances. The Cabinet Committee on investment is working to remove hindrances in the way of stalled
